DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 256,045, dated April 4,1882. Application filed January 9, 1882. (ModeL) To all whom it mayconcern Beit known that I, ISRAEL P. PoULsoN, of Greenfield, in thecounty of Hancock and State of Indiana, have invented certain new anduseful Improvements in Door-Checks; and

I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

Figure 1 is a perspective view of my improved door-check attached to thewash-board of a room. Fig. 2 is a longitudinal central section of thesame.

This invention relates to improvements in door stops or checks, moreespecially to that class in which a rubber buffer is used.

.It is the object of this invention to furnish a stop or check in whichthe buffer is so placed as to avoid the liabilityofits being broken orforced out of place by the impact of the door.

Many stops have been devised and pro ided with buffers; but these aremore or less lacking in qualities which my device possesses. A plate hasbeen used having acurved recess or seat in which is secured a rubber cupby the bolt or screw which holds the plate in place. This plate, withits cup, is secured to the door, and such plate is so thin that the knobof the door would strike the wall before the buffer would. Hence anauxiliary stop has to be secured to the wall, against which said latterstop the buffer strikes, the end of the stop taking into the cup. Thisrequires an exact position, and as the door swings the stop on the wallis liable to miss the interior of the cup, and striking against its edgeto jam it and force it out of its curved seat. In my device this is allavoided, as will be shown.

The invention consists in the device hereinafter set forth and claimed.

In the annexed drawings, the letter P indicates a stud having a greaterlength than the ordinary knob of adoor. This stud has a longitudinulbore, 1), and at its outer end an enlargement of said bore, forming acylindrical recess, a, having a bottom which forms a sharp corner, 0,with the sides. In this recess is placed the rubber cup B, which has thesize and shape of said recess and tits it snugly. The edge of this cupis beveled off on the outside, as shown at b, the interior beingcylinrecess keeps the cup firmly in place, the sharp corner holding ittight and preventing it from being pushed out of place; at the sametime, owing to its cup shape, the edge of the rubber can yield to theshock. The bevel at the edge makes it sensitive to slight blows, andheavy ones are taken by the full resiliency ofthe entire cup. The cup,being held loosely, can be turned to accommodate for any unevenness ofwear which may occur.

I layno broad claim to astud having a rubber buffer at its end; but

What I do claim is- A door-check consisting of the following parts, towit: a stud, P, made longer than an ordinary door-knob, and having thebore 10 and enlargement a, provided with a sharp corher, 0, at thebottom, the rubber cup B, made of a size to snugly fit the enlargementor recess a, and the bolt S, passing through the cup and stud, andhaving a screw-thread for securing the device in place, all as setforth.

In testimony that I claim the foregoing as my own invention I affixmysignature in presence of two witnesses.
